GAS-LAMP.

Beit known that LJACQUES BRAUNs'rErN, ven ineer, a citizen. ofRoumania,residing at 9 asserthorstrasse, Berlin, Germany, have invented certainnew and useful Im rovements in Gas-Lamps, of which the fo owing is aspecification.

This invention relates to as-laxnps, `and Qmore particularly to lamps`or inverted in- 'candescent gas-light..

v4The invention substantially consists in the .1' providing of meanswhich facilitate the invserting of the incandescent mantles,in the' lam1 i oreover, the invention consists in certain i novel features by whicha considerably is a plan' of the plate whichbears the mant es.

Fi 3 is a vertical central section of a modifie l form 'of the lampsubstantially adapted for use in open air.

llis a suppl pipe to a as-charn r2.

3 es ignates mixing-tubes which are fed with as from the gas-chamber 2and are for the gas which leads 5 designates incandescent mantles whichare so ositioned that same take up the mixturefo gas and air leaving themiXin -tubes 3.

' 6 is aplate which isprovided wit holes 7 adapted to receive themixing-tubes 3.

'f8 designates carrying-rings for the incandescent .mantles Each ring.is provided' with lugs9", having horizontally-projecting arts10,'.adaptedfto rest on the edge of the lioles 7 of plate6. Thehorizontally-project arts 10 .are provided each with a step u later on.

V5e .-'12 designates a lar 'p6 and adapted to e he d by a supportingmember.. so as to secure the position of car-A rier-plate 6 andincandescent mantles, 5 in re-l .lation to the mixing-tubes 3.

or a'purpose which will become clear" pieces fixed toplate on thedrawings. For this reason the same reference-numerals are used fordesignating the said parts in all the figures.

Now referring more particularly to Fig. 13 is an annular rosette,whichis' connected with the lamp b a hinge 14 and which-has a.horizontal -annu ar part l15, forming asupi port for theabove-mentioned rectangularv ieces 12. 16 is a glass shade rovided witholes 17 and mounted to the ed rosette 13. 18 is a screw sec the annularro-l sette 13 and glass'shade 16 m operative posi? tion, as shown in thedrawings. 19 is a cylinder provided with two rows of openings 20 21. 422is a cross-wall for l said cylinder 19 and so positioned thatit crossesthe mixing-tubes 3 between vtheir `open ends and the air-inlets 4. Thecrosswall 22 forms a deflector for theAv hot gases and is provided witha curved extension .part 23. 24 is a hood which surroundsthe 'upper acoverfot- Pmnted Nov. e, 190e.

which is fix tance therefrom, leaving a free lspace 26y fortheescapementof the gases.

The operation of the lamp isv as follows: Atmos heric air enters throughslits 20.andl` cools the arts' above the deiecting' cross-wall 22. -T 'sair is drawn 'into the:

mixing-tubes 3 through holes 4 and -together with the gas, thecombustible-finir" ture for heating the mantles -5 to incandesf cence.The hot gasesV of combustion'and the'l air entering through cpeni 17into: the glass shade are checke by t e defieotor 22 23 and flow intothe atmosphere through -the free space 26 between deilector 23 andrefiec? If it is intendedfto provide the lamp with' new mantles, therosette 13 .with glass shade 16 is turned on pivot 14, so as to .givefree access to the top. opening of the rosette;13. Now an angular piece12 1s grasped, and thus the plate 6, with the incandescent mantl'es 5and carrying-rings 8, taken out of the lamp;

On grasping one of the horizontal projections 10, supported by plate 6,the corresporidi to the deilector 23 in adibincandescent mantle can bepulled throug the corresponding hole of late 6 and a'new mantle 'fixedto a ring 8 wit lugs 9, and hori# -zontal projections 10 may be down.wardly through the-said hole from the top side of plate 6 untill theV`horizontalprojo.-.
